Verfahren zur UEberwachung und Anregung der Herztaetigkeit

摘要

The intensity of the stimulation pulses from the output stage is increased step-by-step to an adjustable maximum value by a regulating stage. The latter is fed pulses derived from the activity of the heart. When these pulses are absent or late, the value of a shunt combination of resistances is increased in steps until an adjustable maximum value is reached, as determined by a potentiometer connected in parallel with these resistances and also connected to the control electrode of a component in the output stage.
